Title:
LIGHT-DIFFUSING RESIN COMPOSITION AND PART MOLDED USING SAME
Document Type and Number:
WIPO Patent Application WO/2013/161843
Kind Code:
A1
Abstract:
This light-diffusing resin composition contains a transparent resin (X) and cross-linked resin microparticles (Y). The absolute value of the difference between the refraction index of the transparent resin (X) and the refraction index of the cross-linked resin microparticles (Y) is 0.095-0.115. The volume-average grain diameter of the cross-linked resin microparticles (Y) is 1.5-3.3 µm. The variation coefficient when the volume-average grain diameter is measured is no more than 20%. When the cross-linked resin microparticles (Y) are pyrolyzed in a nitrogen-gas environment with the temperature increasing by 10°C/minute. The temperature at which the mass is reduced by half is at least 320°C.
